CAR-UNDERFRAME.

Application filed March 11, 1916. Serial No. 83,590.

Be it known that I, ROBERT R. IVEAVER, a

. citizen of the United States, and a resident of Columbus, in thecounty of Franklin and State of Chio, have invented certain new anduseful Improvements in Car-Underframes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in car underframes and moreparticularly to the construction of the cross bearers and the connectionof the same with the center girder and side sills,-an object of thepresent invention being to provide a substantial cross bearer, the outerend of which shall have an extended connection with the side sill andstill be in a plane below that of the top of the side sill and alsobelow the plane of the top of the inner end of the cross bearer.

With this and other objects in view, the invention consists in certainnovel features of construction, and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a sectional view showing anembodiment of my invention, and Fig. 2 is a fragmentary view taken atright angles to Fig. 1.

For the purposes of this case it will suffice to show and describe asingle cross bearer and its connection with the center girder and sidesill.

l represents a center girder and 2 a side sill, the latter being shownin the drawing as being of channel form with its upper and lower flangesprojecting inwardly.

My improved cross bearer 3 is preferably made of pressed steel ofgeneral channel form, having upper and lower flanges 4-5 and a verticalflange 6 at its inner end. rIhe cross bearer has a general taperingshape with its larger end approximately equal to the space between theupper and lower flanges of the center girder,-said larger end of thegirder being disposed between said upper and lower center girder flangesso that its top shall be below the plane of the top of the centergirder, and the vertical flange 6 at the larger inner end of the crossbearer is disposed against the web of the center girder so that it maybe secured thereto.

The smaller outer end of the cross bearer enters between the inwardlyprojecting fianges of the side sill 2 and the web of this smaller outerend 7 of the cross bearer is extended upwardly as shown at 8 and theupper flange of the cross bearer is omitted from the maj or portion ofsaid upward web extension. The extended outer end 7-8 of the crossbearer is secured to the web of the side sill by means of an angle iron9.

It will be observed that the connection of the cross bearer to the sidesill is below the upper flanged edge of the side sill; that the top ofthe enlarged inner end of the cross bearer is below the plane of the topof the center girder and above the plane of the top flange at the outerend of said cross bearer, and also above the top of the extended web atsaid outer end of the cross bearer, and that the top of the side sill isslightly above the plane of the top of the center girder and coincidentwith the floor line.

In the drawing, I have shown a cover plate 10 which extends over thecenter girder and partly over the cross bearer, and I have also shown aZ-beam 11 for supporting the floor intermediate the ends of the crossbearer.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is

1. The combination with a center girder and a side sill, of a crossbearer having a gen-eral tapering shape with its wider end secured tothe center girder, said cross bearer having upper and lower longitudinalflanges, a portion of the upper flange being omitted j at the smallerend of the cross bearer and the web of said smaller end being extendedabove the flanged edge thereof, said extended web portion being confinedbetween the upper and lower edges of the side sill, and an angle membersecured to said extended web portion and to the side sill wholly betweenthe upper and lower edges of the latter.

2. The combination with a center girder, and a side sill having inwardlyprojecting flanges at its respective edges, of a cross bearer having ageneral tapering form and provided with upper and lower lateral flanges,the smaller end of the cross bearer o the top ofthe extended web at thesmaller l0 end of said cross bearer.

In testimony whereof, I have signed this specification in thepresencegof twosubseribing -V witnesses.
